Short on PP_VDD_Main but no heat
Hi,
I have a rare problem. Normally i fix a short in just a few minutes. But on this board i have checked several times now, without any luck.
I inject from 1 - 4.2A to the pads. Voltage down to around 0.9V, So heat should not be a problem?
I use the rosin method, removed all shields and covered the WHOLE board. Can’t find any heated component at all.
Any ideas how to proceed?
